AlertView using Swift iOS

AlertView using Swift iOS

In this tutorial i am going to discuss how to create AlertView using Swift Language.

Create a new Project

• Select Xcode => File => New Project
• Select Single View Application
• Name your Project
• Save as AlertView Demo

Here we are going to three types of AlertView’s

Create a UserInterface to Show Alerts, here i created three buttons to show three different Alerts.

Alert 1

Create a action for button and show your Alert in the Action

@IBAction func simpleClicked(sender:AnyObject) {
        
    let alertController = UIAlertController(title:"Title", message: "A Short Message", preferredStyle: .Alert)
        // Create the action.
        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { action in
            NSLog("The simple alert's cancel action occured.")
        }
        
        // Add the action.
        alertController.addAction(cancelAction)
        
        presentViewController(alertController, animated: true, completion: nil)

    }

 Alert 2

@IBAction func okClicked(sender:AnyObject) {
    
        
        let alertCotroller = UIAlertController(title: "Title", message: "A Short Message", preferredStyle: .Alert)
        
        // Create the actions.
        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { action in
            NSLog("The \"Okay/Cancel\" alert's cancel action occured.")
        }
        
        let otherAction = UIAlertAction(title: "OK", style: .Default) { action in
            NSLog("The \"Okay/Cancel\" alert's other action occured.")
        }
        
        // Add the actions.
        alertCotroller.addAction(cancelAction)
        alertCotroller.addAction(otherAction)
        
        presentViewController(alertCotroller, animated: true, completion: nil)
        
    }

Here we can add as many buttons you want in your Alert and provide action for it.

Alert 3

@IBAction func textEntryCllicked(sender:AnyObject) {
        
        
        let alertController = UIAlertController(title: "Alert", message: "A Short Message", preferredStyle: .Alert)
        
        // Add the text field for text entry.
        alertController.addTextFieldWithConfigurationHandler { textField in
            // If you need to customize the text field, you can do so here.

        }
        
        // Create the actions.
        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { action in
            NSLog("The \"Text Entry\" alert's cancel action occured.")
        }
        
        let otherAction = UIAlertAction(title: "OK", style: .Default) { action in
            NSLog("The \"Text Entry\" alert's other action occured.")
        }
        
        // Add the actions.
        alertController.addAction(cancelAction)
        alertController.addAction(otherAction)
        
        presentViewController(alertController, animated: true, completion: nil)
        
    }

We need to add Textfield to our Alert . if you want to provide a password (secure ) field we need to enable secureTextEntry.

textField.secureTextEntry = true

Add this line into your Textfield  method when you are adding it.

Run your Project and see the output…

Here is the Code
